Abstract

The utility model relates to a rice hull powder burning device. A feeding device of a conventional rice hull powder boiler has the defects of poor burning stability, load fluctuation, low combustion efficiency and the like caused by non-uniform mixing of rice hull powder and primary air due to poor feeding continuity and poor feeding stability. The rice hull powder burning device consists of a rice hull powder quantitative feeding assembly, wherein the rice hull powder quantitative feeding assembly is connected with a rice hull powder and primary air mixing assembly; one end of the rice hull powder and primary air mixing assembly is connected with a primary air duct assembly; and the other end of the rice hull powder and primary air mixing assembly is connected with a rice hull powder combustor nozzle. The rice hull powder burning device is used for realizing continuous, stable and uniform powder supply for the rice hull powder boiler, and the mixing proportion of the rice hull powder and the air can be flexibly adjusted according to the burning load; and meanwhile, air and powder are mixed uniformly, and the rice hull powder can be burned strongly, fully and efficiently.

Description

A kind of powdered rice hulls burner
Technical field:
The utility model relates to biomass combustion equipment, is specifically related to a kind of powdered rice hulls burner.
Background technology:
The stable operation prerequisite of combusting rice hull powder boiler: the feeding of powdered rice hulls continous-stable, the powdered rice hulls that feeds simultaneously evenly mixes with wind and is carried, and sends into boiler combustion through powdered rice hulls burning spout.For powdered biomass, its particle rough, and out-of-shape, there are many burrs in the surface, often have stronger adhesiveness between particle, have characteristics in light weight, that density is little, the angle of repose is big simultaneously, these factors directly cause the flowability of powdered biomass particle poor.The charging gear of existing powdered rice hulls boiler exists feed continuity, poor stability, and then powdered rice hulls is inhomogeneous with mixing of a wind, causes problems such as boiler combustion instability, load fluctuation, efficiency of combustion be low.
Summary of the invention:
The purpose of this utility model provides a kind of powdered rice hulls burner.Realize the powdered rice hulls boiler continuously, stable, supply powder uniformly, can adjust powdered rice hulls and Air mixing proportioning flexibly according to the burning load situation, guarantee that simultaneously the wind powder mixes, guarantee that the powdered rice hulls burning is strong, fully, efficiently.
The purpose of this utility model is achieved in that
A kind of powdered rice hulls burner, its composition comprises: the powdered rice hulls dosing assembly, the other end that described powdered rice hulls dosing assembly is connected with the electric hybrid module of described powdered rice hulls and a wind, electric hybrid module one end of described powdered rice hulls and a wind is connected airduct assembly, described powdered rice hulls and the electric hybrid module of a wind is connected the powdered rice hulls burner nozzle.

Described powdered rice hulls burner, a described airduct assembly comprises volume damper, wind jet pipe and blower fan, the outlet of described blower fan connects volume damper, described volume damper connects the straight section pipe, described straight length connects a wind jet pipe, and described straight section length of tube is not less than 1.5m.
Described powdered rice hulls burner, the electric hybrid module of described powdered rice hulls and a wind comprises material blanking tube, injection mixing chamber, described material blanking tube connects the injection mixing chamber, and described injection mixing chamber connects described powdered rice hulls burner nozzle, and described material blanking tube adopts vane type or board plug type.
Beneficial effect:
1. the material level in the utility model shell powder storehouse keeps being not less than 500mm in normal course of operation, avoids air to be sucked into injection mixing chamber, influences the proportioning of wind and powdered rice hulls.
Powdered rice hulls described in the utility model and a wind electric hybrid module are realized a wind carrying and evenly mixing powdered rice hulls at the injection mixing chamber.
The principle of the static energy when the utility model utilizes a wind flow and kinetic energy conversion, in powdered rice hulls feeding mouth position, arrange a wind jet pipe that shrinks, a wind is with higher speed ejection, in the process of ejection, the static energy of a wind changes kinetic energy into, produce local low pressure, the powdered rice hulls that blanking port falls into is sneaked into wind one time, and is carried and enters mixation tube section, finish sufficient mixing, spray into the combustion chamber.
The outlet in the utility model powdered rice hulls storehouse connects the entrance of powdered rice hulls flow control valve, the material level in described powdered rice hulls storehouse, in normal course of operation, keep being not less than 500mm, the outlet of described powdered rice hulls flow control valve connects material blanking tube, and form can be regulated custom employing vane type or board plug type according to boiler capacity and operation.Described pressure fan outlet connects volume damper, and described volume damper connects the straight section pipe, and described straight length connects a wind jet pipe, and described straight section length of tube is not less than 1.5m.The outlet of a described wind jet pipe is installed in the axial location of material blanking tube, and the muzzle velocity of a described wind jet pipe is not less than 25m/s; A described wind jet pipe all is connected the injection mixing chamber with material blanking tube, and described injection mixing chamber connects the powdered rice hulls burner nozzle, and described injection mixing chamber cross section wind speed is not less than 18m/s, and the cross section wind speed of described powdered rice hulls burning spout is not less than 13 m/s.Realized the powdered rice hulls boiler continuously, stable, supply powder uniformly, can adjust powdered rice hulls and Air mixing proportioning flexibly according to the burning load situation, guarantee that simultaneously the wind powder mixes, guarantee that the powdered rice hulls burning is strong, fully, efficiently.
